🔹 Top 4 Chess Opening MISTAKES After 1.e4 –

In this video lesson, GM Igor Smirnov will teach you how to deal with the annoying pins on your knights when your opponents play Bg4 or Bg5. You will learn the scenarios when this move is playable and when it is a bad mistake (or opening error).

Most amateur chess players play this move without a clear purpose. And sadly, most players don’t know how to punish this opening mistake either. That is exactly what you will learn from this video lesson. You will also learn how to launch a devastating kingside attack on your opponent’s castled king.

  1. I don't know, man. I think calling 6.Bg5 a mistake is incorrect. After 6… h6, 7.Bh4 is the real mistake, allowing 7…g5. Instead 7.Bxf6 Qxf6 8.Nd5 should maintain a small edge for white. Still 6.Na4 may be a better try for advantage.

  2. Well that's true but It only works if the bishop retreats instead of capturing the horsie and then fighting in the center, witch Is how I usually play that pin to avoid loosing tempos

  3. Да прост на русском бы говорил

  4. This is exactly why Ukraine will win this war. Ukrainians like Igor are smarter.

  5. The pin is very good IF the d5 or d4 square comes as an outpost for the knight (if the C and E pawns are pushed) then whoever gets the posted knight will have an easier endgame.

  6. My opponent is also watching this😂😂😂

  7. Why not to take the knight? And if that happens, what it's the plan if you have the bishop pair, if you are facing the bishop pair, etc.

  8. 2:52 No way to defend the pawn? How about Q back to d1? Yes all defended. Then Bb5! with the Knight supporting.

  9. This video ended my 30 game losing streak to Arthur-bot, Thanks!

  10. after h6 the bishop h5 g4 Kg4 white is in trouble

  11. What if at 1:29 white sacs the knight for 2 pawns and plays queen f3? Can black save the knight that is pinned?

  12. Thank you! This seems like a great strategy to me!

  13. Sir i am an 1650+ lichess player and when I calculate I am narrow minded and many tactical mistakes. I give sac thinking that if he plays one move I would win but he plays the other defense which leads to lose in game. How to not play without tactical mistake and to precise calculation. Pls help. You should be the to help me.

  14. this is how i destroy 2000s at my level. i studied this line with stockfish after one loss as white with this, and started this. i have this one trap like with 1. bg5 h6 2. bh4 g4 bg3 ( if king is castled ) nh5 preparing takes on bishop.if h3 free bishop on the way ( since the pin with black squared bishop is controling it ) so you win. won many times with this way and still works!!

  15. wow! this was a really well explained opening mistakes. Keep it going! thank you

  16. What's happening if the bishop takes the knight instead of retreating?

  17. it feels weird that with white the ruy lopez that pins the knight is a very good opening and is very solid even by engine standards

  18. him: most common mistake in the opening stage, pinning the knight
    gms: rUy lOpEz

  19. I only clicked the video because it's both well-titled and 200K views. It turns out to be well-done indeed.

  20. Bg5 in the first position isn’t a mistake, not even incorrect. Bushop takes knught and most continuations favor white still. 2nd line is a mistake from white

  21. Honestly i dont ever see these lines. No one with 1000+ rating would allow many of the lines you are proposing moving the bishop back literally just allows your oponent free development… and if it is allowed it would be specifically to break down the kingside structure… i feel like this tutorial is extremely niche and as a general rule eould be extremely misleading…

  22. What if bishop takes white knight on F6? Would you say that's a mistake from the white? Because that's what I get most of the time, they pin my knight at first but then they catch it

  23. When they try to kick the pinning bishop, most of the time I just take the knight though.

  24. In your masterclass, you talk about the need to castle early, but here, it seems to be just the opposite ???

  25. The best chess Video tactic for beginners n intermediate I've seen and I've seen a lot…

  26. @1:50 can white play h2 to h4? Allows bishop a square to move to, if black trades pawns bishop is free and can re-pin the queen, and if black advances the pawn to g4 the knight can move. I feel like i'm missing something

  27. Ok, what if bxf6? Why only fixiate on bh4

  28. Any tips how to handle this pin after castling? Or just play around it

  29. This video and the other similar one with bishop out bedside knight were great for a beginner , thank you. After I started recognizing it more wins came after .

  30. I am a beginner play for fun and spend time. I actually lost many games with this pin after I learned to castle on the short side. Thanks for explaining and I am hoping to apply the tactics.

  31. At first around 2:30 I was like… hey what if Bh7 though in order to threaten g4, then what do you do since you’re being forced to play BxNf3 to which white then doesn’t have to ruin their pawn structure and can play QxBf3… and that is when I realized that black has no problem if they don’t ruin the pawn structure, and they would LOVE for QxBf3…

    The followup is still Nd4 from black but it’s even nastier than his example… that Queen is TOAST if white made that exchange and then did anything but go right back to d1 after Nd4 attacks.

    Every possible square becomes death for the queen or a king/queen fork if it doesn’t return to d1, so the result is that you just removed white’s strong center defending knight on f3, gave up your light square bishop which was weak anyway aside from the pin it delivered (which was about to fall to g4 by white anyway) and then ended up in basically the same position as 2 moves prior on white’s end, but black is now up a tempo and completely centralized with Nd4 while white is basically sitting there like they never did anything and their knight on f3 just magically disappeared, plus their bishop on h7 would be just sitting there eyeing down endless black pawns chained together- unable to really ever enter play again without a tactical pawn break or multiple moves back and forward again postponing the white king castling for even longer.


  32. Редкий русский шахматист, который не зануда, не сумасшедший, не гопник (как Витик), а просто приятный человек ! 👍

  33. Why after Bg5 there isn’t Bxf2+, Kxf2, Ng4+, Ke2 (for example) and Qxg5

  34. I would have liked to see the full bishop retreat discussed a little. So many variations, I try to watch the speed players navigate the positions and maybe get a development instinct rather than full memorization dependence, but you show the positions and development very well. I don't play the London, everyone loves it, why dissect it further lol. Great video though.

  35. Oh! Thanks a lot Igor for another so Good video about this opening! 😊👍♟
